前言
虽然使用rpm包安装比较简单、快速，但是在功能上存在局限性，所以使用源码包安装。使用源码编译的方式安装软件，服务器上需安装开发环境，针对本服务器的版本，需安装gcc。而不搭建本地yum源，是无法使用yum install gcc等命令安装gcc的，故先搭建本地yum源。
搭建本地yum源
1、拷贝光盘文件（例如RHEL-Server-5.4-x86_64-dvd.iso）中的Cluster、ClusterStorage、Server、VT文件夹至本服务器中，例如/iso目录中
# cd /iso# lsCluster  ClusterStorage  Server  VT# du -sh /iso3.2G    /iso2、使用vi命令修改/etc/yum.repos.d/rhel-debuginfo.repo文件。即# vi /etc/yum.repos.d/rhel-debuginfo.repo
           注：主要是修改​​baseurl=file:///iso/Cluster/和gpgcheck=0。​​pgpcheck是否使用gpg验证RPM包的不可抵赖性,设为0可以省不少事。主要是Server那个目录换成0.就行了，其它的很少用到的。

# cd /iso/Server# 进入/iso/Server目录，可以看见许多rpm包# rpm -ivh createrepo*warning: createrepo-0.4.11-3.el5.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 37017186Preparing...                ########################################### [100%]1:createrepo             ########################################### [100%]# createrepo /iso/Server/3039/3040 - jakarta-commons-collections-testframework-javadoc-3.2-2jpp.3.x86_64.3040/3040 - tomcat5-jasper-5.5.23-0jpp.7.el5_3.2.x86_64.rpmSaving Primary metadataSaving file lists metadataSaving other metadata4、现在yum命令就可以使用了
安装gcc编译开发环境
1、使用yum命令安装gcc
# yum install gcc 或 # yum install -y gcc2、查看是否安装成功
# gcc --versiongcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-46)Copyright (C) 2006 Free Software Foundation, Inc.This is free software; see the source for copying conditions.
